Be a kind of diaphragm pump as illustrated in fig. 1 and 2, comprise the first chamber 1, the second chamber 2 and an air valve device 3, two chambers connect by a rod end chamber (not shown), this rod end chamber comprises a piston rod 4, it is not shown that these piston rod two ends are connected with two piston 5(the other end pistons), these two pistons lay respectively in the first chamber and the second chamber, and piston is diaphragm; That be positioned at the first chamber is diaphragm A, and that be positioned at the second chamber is diaphragm B; Respectively be provided with inlet opening, liquid outlet opening and inlet hole, air outlet hole (not shown) in two chambers; This air valve device is installed in the diaphragm pump outer surface and is connected with air outlet hole in the chamber; The first chamber be connected the inlet opening of chamber and connect respectively the liquid inlet pipe (not shown), the first chamber be connected the liquid outlet opening of chamber and connect respectively the drain pipe (not shown).
This diaphragm pump surface is equipped with air inlet system with respect to the position of inlet hole, and this air inlet system is connected with inlet hole; Air inlet system comprises pilot valve 6 and suction port end cap 7, and pilot valve is installed in the diaphragm pump outer surface with respect to the position of inlet hole by a pilot valve pad 8, and the suction port end cap is installed on the pilot valve by an end cap pad 9, and above-mentioned parts connect by screw 10.
Comprise a cavity in the piston rod, this cavity connects two chambers, is used for transmitting pressurized air.
Between diaphragm and two chambers by outer compressing tablet 11 be connected compressing tablet 12 and carry out compressing tablet and be connected.
Also comprise a charging base 13 in this diaphragm pump, the charging base comprises supply pipe 14 and material feeding mouth 15 of a both ends open, described material feeding mouth is positioned on the described supply pipe and with described supply pipe and is communicated with, and the two ends of described supply pipe connect respectively the liquid inlet pipe of described the first chamber and the liquid inlet pipe of described the second chamber; The position that is connected with liquid inlet pipe respectively at the supply pipe two ends respectively is provided with a valve ball 16, and this valve ball is used for the open and-shut mode of control liquid inlet pipe.
Also comprise a discharging base 17 in this diaphragm pump, the discharging base comprises discharge nozzle 18 and discharge port 19 of a both ends open, described discharge port is positioned on the described discharge nozzle and with described discharge nozzle and is communicated with, and the two ends of described discharge nozzle connect respectively the drain pipe of described the first chamber and the drain pipe of described the second chamber; The position that is connected with liquid outlet respectively at the discharge nozzle two ends respectively is provided with a valve ball 20, and this valve ball is used for the open and-shut mode of control drain pipe.
The working principle of this diaphragm pump is: air valve device is introduced the first chamber to pressurized air, i.e. the back side of diaphragm A.Pressurized air is intercepted by the elastomeric septum sheet and separates with liquid.Barrier film is not only cut apart assembly as one, and can play the effect of balance pressure reduction, elimination mechanical stress.Pressurized air is pushed diaphragm A to first chamber from the center.Another sheet diaphragm B is connected to the piston rod pulling of pressurized diaphragm A.This moment, diaphragm B was in suction lift, and the air at its back side is discharged in the atmosphere by the discharge port of pump.Diaphragm B moves to make in the second chamber to the center of pump and forms vacuum.Atmospheric pressure is pressed into liquid the supply pipe of pump, valve ball is pushed open from its valve seat, so liquid is freely by valve ball and fill with the second chamber.
When pressurized diaphragm A reached its position limit, air valve device changed guiding, pressurized air was supplied with the back side that imports diaphragm B.Air pressure pushes away the center with diaphragm B, and connected piston rod pulls to the center with diaphragm A.This moment, diaphragm B was in discharge stroke.The hydraulic pressure that produces in the second chamber and pump arm presses to its valve seat with the import valve ball, again the outlet valve ball is pushed open from its valve seat simultaneously, and the outlet valve ball of opposite side is but closed, and this moment, liquid was discharged via the left side outlet stool of pump.Diaphragm A just shifts to the center, forms vacuum simultaneously in the first chamber.Barometric pressure is pressed into liquid the import of pump, and the import valve ball pushed away from valve seat and allows liquid enter in first chamber on right side.
After finishing a whole stroke, air valve device is introduced pressurized air again the back side of diaphragm A, and this moment, diaphragm B was in induction stroke.When pump was returned to starting state, two diaphragms in the pump had been finished a process that sucks and discharge separately, and this has just consisted of the process of a circulation pumping.By use condition, pump need to just can make pumping reach completely self-priming state by the pump action that circulates completely for several times.
